      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usb-audio: Add sanity check for OOB writes at silencing\n\nAt silencing the playback URB packets in the implicit fb mode before\nthe actual playback, we blindly assume that the received packets fit\nwith the buffer size.  But when the setup in the capture stream\ndiffers from the playback stream (e.g. due to the USB core limitation\nof max packet size), such an inconsistency may lead to OOB writes to\nthe buffer, resulting in a crash.\n\nFor addressing it, add a sanity check of the transfer buffer size at\nprepare_silent_urb(), and stop the data copy if the received data\noverflows.  Also, report back the transfer error properly from there,\ntoo.\n\nNote that this doesn't fix the root cause of the playback error\nitself, but this merely covers the kernel Oops.",
